BAG-CLOSING DEVICE.

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed August 9. 1906. Serial No. 329875.

T 0 all whom "it may concern:

Be it known that I, LARS Ron, of the city of Montreal, in the Provinceof Quebec and Dominion of Canada, have invented certain new and usefulImprovements in Bag-Closing Devices, of which the following is a full,clear, and exact description.

My invention relates to "bag closing devices, and its object is toprovide a simple and inex ensive means for securely closing the mont 1of a bag or similar article.

A further object is to provide a bag tie which will be durable and offew parts, and which may be used repeatedly without being liable todamage by rough usage.

To accomplish these objects I provide a curved body member, of anysuitable material, having a slot therein containing an eccentricallypivoted cam, having notches in the curved face thereof to engage alocking catch. A strip of leather or other suitable material, fixed atone end to the body member and at the other end adapted to pass betweenthe cam and the end wall of the slot complete the device.

In the drawings which illustrate my inventionz Fignre 1 is a perspectiveview of the device in operation. Fig. 2 is a vertical section on theline 1-2 of Fig. 3. Fig. 3 is a plan view of the device.

Referring to the drawings, 3 designates a bag and 4 the curved body ofthe closure device having a slot 5 therethrough. A cam 6 iseccentrically pivoted at 7 in the slot 5 and is provided with notches 8in its curved face 9. The curvature of one side of the cam is broken bya flat face 10, the purpose of which will be hereinafter explained. Astrip of leather 11, or other suitable material, is fixed to the body at12, and the free end is passed between the wall 13 of the slot 5 and thecam 6. A catch 14 is pivotally secured to the body at 15 and its freeend 16 is adapted to engage the notches S in the cam 6.

The operation of the device consists in passing the loop, shown in Fig.2, around the gathered neck of the bag and then pulling the loop astightly as possible. The eccentrically pivoted cam 6 does not oppose theoperation of drawing the strap in one direction, but as soon as the loopis made sufficiently tight, the cam 6 is partially rotated in thedirection of the arrow in Fig. 2 so that the edge 17, formed by themeeting of the faces 9 and 10 engages the leather strip 11 and forces itagainst the wall 13 of the slot 5. Any tendency to stretch the loopwill, owing to the eccentricity of the cam 6, force the edge 17 closerto the wall 13. To loosen the closure device, it is only necessary togive the free end of the leather strap a quick pull or jerk by whichmeans the edge 17 is released and the cam partially rotated in abackward direction. To prevent an accidental jerk on the end of thestrap 11 from loosening the grip of the cam 6, I provide the auxiliarycatch 14, which is adapted to swing outwardly, as shown in Fig. 3. henthe cam is in locked position, this catch is turned so that its end 16engages one of the notches 8, thus securely locking the cam againstaccidental displacement.

The advantages of this device will be obvious. A considerable saving oftime and labor is efl'ected in the tying operation, while the contentsof the bag are secured during long transportation.

Having thus described my invention so that the same may be readilyunderstood by those skilled in the art to which it appertains, what Iclaim and desire to secure by Letters Patent is 1. In a device of theclass described, a curved body member having a slot therein, aneccentrically pivoted cam operating in said slot and provided with aplurality of notches in one side thereof and an angular corner on theopposite side thereof, a closure strap fixed at one end to said curvedmember and having its other end passing between the angular corner olsaid cam and the wall of said slot, and a pivoted locking catch adapt edto engage the notches of said cam.

2. A bag tie comprising a body member having a slot therein, a pivotedeccentric operating in said slot and provided with a plurality ofnotches at one side thereof, a closure strap fixed at one end to saidcurved member and adapted to be gripped between the eccentric and thewall of said slot, and a curved locking catch adapted to engage thenotches of said eccentric.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

LARS ROD.
